Full Changelog: v1.16.0...v1.16.1

v1.16.0

The v1.16 release of the Dapr .NET SDK delivers a set of targeted enhancements focused on developer productivity and runtime efficiency. Most notably, this version debuts Roslyn analyzers and accompanying code fixes that enforce best practices around SDK configuration and usage. This marks the beginning of a more guided and prescriptive development experience, reducing setup complexity and surfacing misconfigurations early.

Framework support has been consolidated with the depreciation of .NET 6 and 7, aligning the SDK with .NET 8 and 9. This shift enabled internal refactoring that improves performance and resource utilization across core components.

On the feature front, the SDK now supports the latest capabilities in the Dapr conversation API with tooling, as well as the overwrite flag for job scheduling. A critical bug affecting encryption and decryption of large files exceeding 4 GB has been resolved.

Dapr Workflows orchestrated using the .NET SDK are now considered stable, supporting both short-lived and long-running processes. Performance has been further improved through targeted optimizations, including new helper methods that enable deterministic parallelization with bounded concurrency.

Maintainer's Note

I wanted to share a special shout-out to everyone that participated in this release. Without your work to find and report issues in Discord or GitHub, spot documentation inconsistencies, request features, submit pull requests, review others' pull requests or even just use the various parts of the Dapr .NET SDK in your projects - I heartily appreciate the effort you've put into this project. The project wouldn't be what it is without your help. Thank you!

v1.16.0-rc03

What's Changed

• The protos used by durabletask were slight inconsistent with those used by the Dapr runtime (as they used the latest from microsoft/durable-task). These have been updated acordingly.

Full Changelog: v1.16.0-rc02...v1.16.0-rc03

v1.16.0-rc02

This is a follow-up to the v1.16.0-rc01 prerelease build deployed last week and fixes another related set of issues that came to light after the outer timeout issue was discovered.

Like the rest of the 1.16 releases will be, this only supports the .NET 8 and .NET 9 targets and does not support .NET 6 or .NET 7. That said, like the previous 1.16.0-rc01 prerelease, this also excludes all the 1.16 feature releases and is fully compatible with the latest 1.15 Dapr runtime.

Please don't hesitate to reach out for assistance here or via our Dapr Discord channel if you have any questions about this.

What's Changed

• Durable task package update by @WhitWaldo in #1546

Full Changelog: v1.16.0-rc01...v1.16.0-rc02

v1.16.0-rc01

This is an out-of-band patch release to address an issue raised with workflows timing out and reconnecting frequently when they're either idle or activities run for a long period of time.

It is released as a release candidate on the 1.16 series because it only supports .NET 8 and .NET 9 targets (which 1.16 will be limited to as well) and does not also include support for the .NET 6 and .NET 7 targets that 1.15 targets.

That said, none of the functionality currently being built out for the 1.16 release is included in this RC, but it does include all the patches up to the most recent 1.15 release, so if you're targeting .NET 8 or .NET 9, you should be able to safely consume this package without fear of significant changes more common to the main Dapr releases.

v1.15.4

What's Changed

• Updating gRPC and Microsoft.DurableTask.* packages by @WhitWaldo in #1523

This release fixes a reported issue regarding issues connecting (and reconnecting) to the scheduler when using .NET 9 and Dapr.Workflows.
